Dear Mr. Cembrola,
why would you like to go the hard way an try to build you own
PIC-programmer and even
write your own software ?

Maybe we can help with a complete programmer ?  Our P16PGD is able to
program over 45 different PIC-chips.
And it is very easy to implement new PICs, simply add them to the
parameter list. It is very low priced (only 198 DM) and it comes
complete with the powersupply, the connecting wires and so on. The
software is
also included (it is shareware !) and it is updated on a regular bases.
Have a look at our site at :

sorry, it's only in german right now, but it will be available in
english soon.
If you need more information (also in english), just contact us.
